5 plet'ely Be it known that I, LEWIS C.-Psn1mn, a citizen of the UnitedStates,resi at Rochester, in the county of Wayne an State of New .York,Improvements in Gas-Producers,of which the followingis a s ecification.

. This invention as for its object the construction of an apparatus forthe 'manufacture or roduction of gas from soft coal. To attain t end, -Iuse an ordinary cylindrical steelshell of any desired dimensions havinga hop r uponitstop provided with a valve for-a 'tting the coal andfurther provided with admissions for steam and air and withair-tightr-fitting doors for the removal of ashes and taking care of thegeneration of gas.

The. main ditlicult heretofore in comsoft co has been the forming of alar e ortionof rich vapors at a comparatively ow temperature in thelowerportions of the generator'during g'asification, and the same in outwith'the more perfect gas from the lowerpart; of thefuel-colummarecondensed to a large extent into tarry de osits aswellasliquidandoilycompounds. T erefore to secure all the valuableconstituents possible in the rich heavy vapors which condense readily itis necessary to commingle them with highly-heated vapors and subjectthem to a high temperature while passing through the high-temperaturezone of the generator, where perfect and full decomposition takesplaceby uniting with additional portions of air and steam.

distributing of the fuel-column by means of the bars 23' a fire-brick;lin-,

at 26*, and its upper end provi space'below. The steam and air blastpipe 7 connects with a verticalpipe 8, having a deflecting cap 9, thepipe terminating a of the bed of ashes, as shown at 10. Within upper endof the vertical few inches below the top" the generator-wall 2 areformed three annupassages 11, 12, and 12, which pass eny around withinthe walls, the passage 1 1 eing near the bottom of the generator, thepassage 12 near the top, and the passage 12 about midway.

Direct connection is formed between the passages 11 and 12 by verticalpipes 13 and 14;

Within each of the-pipes 13 and 14 islocated a steam-jet or blower 15and 16. From the annular assage 11 are tapering openings 17,wider at t ebottom than at the top, which prevent clogging and form a passage forgaseous vapors from the passage 11 into the lower part of the generator1, and from the passage 12 are openings 18, wider at the bottom than atthe top,so as to prevent cloggin and which admit of gaseous vaporspassinglrom the upper part of the generator into the passage 12 andthence down the ipes 13 and 14 into the passage 11. Withinthelining-walls islocated a passage 12 extending from the exit-port 20.of the generator around to the vertical pipe 13, the said passage 12'also having communication with the interior of the generator through thevertical tapering openings or slots 21, which are wider at the bottomthan at the top, so as to prevent clogging and which admit of gaspassing from the interior of the generator into the passage12 and on 1through the exit-port 20.

Within the generator between the openlocated the dumpingthe object ofthe same being to support a quantity of coalwhich may be sub'ected to atemperature which will readily a 't of its rich tarry vapors beingdriven out and of the partial eokingof the coal and dumping down on thefuel-column, also toact as a means for the coal,-as desired, over thetop and lever 24.. The said dumping-grate secures a twofold result inthis position. Directly beneath the central part of the grate andsecured thereto is located a gas collector or pipe 25, its lower endbeing 0 en, as shown I ed with slots or o ejmngs 27 around its peripheryor cap for t e free passage of rises from the bottom.

gas from the top as it It will be noticed that the lower end of the pipe25 reaches just below thebottom of the openings 21, leading into theannular passage 12. Therefore it will be observed that the pipe 25 maybe of any convenient size or shape for the purpose of allowing a volumeof gas to pass from the central part ofthe generator to the space abovethe fuel column or under the grate22. J U

To illustrate the operation of my soft-coal, producer, I will assume thegeneratorto be filled with coal from the ash-line to the top of thefuel-column tobe in a state of perfect combustion, asin this conditionwitha slight vacuum within the passage 12 exerted from an 'exhauster(not shown) beyond the outletpipe 20. Therefore the gas from all sidesuniformly will be drawn into the passage 12 and on out through the exit20, while the heat by combustion of the coal-and coke will rise to thetop of the fuel-column and largely gasiiy, and thus coke the upperlayersof coal,

while the highly-heated volume of gas rising and passin directlyupward'in the central portion of t e generator will pass up through Ythe pipe 25 and commingle with the rich vapors the top of thefuelcolumn,,-ca'using a large part of the most easily vaporized con-.stituents in the coal on the grate to distil and'to be sucked'intovtheopenings 18 and down the pipes 13 and 14 by the steam jets I orb1owers15 and 16 to pass into the annular chamber 1 1, thence throughthe ports 17 into the highly-heated zone of the fire, there to becomemingled with additional portions of air and stea1n and ascendingdisassociatedl and forming into a monoxid or producer gas.
